this is player dependant, I've gotten raised on river on seemingly safe cards very often, some players I know to 3bet, and others usually those rockish weak players I just call.

Without a read I am usually just calling, but don't be surprised to regularly see hands like JT/QT or even someone holding an ace who was "slowplaying"

3-bet this [censored] all night long.

Villain looks like he is trying to protect or bluff your A-x out of the pot. HE may often call with a weaker hand.
